The Schedule'refen'ed to in these vLetters Patent: and making part cfthe same vl'o all whom it mag/concern.-` y Y Be it known that I',WILLIAM BAsHoR, of Jobnson City, in the county of Garter and in theState of Tennessee, have invented a new and'usefnl Improvement inFlour-Packers; and I do hereby declare that thefollowing is a full,clear, and exact description of the same, snnicient to enable any oneskilled inthe art to make, construct, and use the same, reference beinghad to the accompanying drawing making part of this specification, inwhiclndrawinginafter be described;

Like letters of' reference indicate Acorresponding parts. Y

A,in the drawing, may represent the .base of the flour-packer.

BeB, upright standards.

O O, cross-beams..

D D, lSliding-standards vor connections secured to the top P, andcarrying the case F.v

G is a movable vertical shaft, carrying a bandwheel, H, and theconical-shaped rollers K K and K' K';

A is the base or foundation ofthe'our-packer, upon -the outer ends ofwhich are firmly secnred,in a suit-- to be mentioned.

G is the vertical revolving shaft, provided at its lower end withsuitable metallicjournals c ccc, bearing the conical-shaped rollers K KK' K', i-n such a'manner that the said rollers may adjust themselveswhile the shaft lis revolving, the rollers acting upon the flour orother material inthe sacks', bags, or other packages.

The rollers K K are made preferably double the size or of a much greaterdiameter than the rollers K K, in order, that the rollers K K; willperform lat least two revolutions'to one revolution of the rollers K K.

The object of employing the large and small vconical rollers-is that,asthe flour is thrown into a case, or conveyed intcfthe same from ahopper or other suitable device, the shaft revolving and the rollerscoming in contactwith the lour,the flour is snugly and closely packedinfthe center, and at the same time forced outward toward the yinteriorsurface of the sacks by the small rollers, when the rollers K K,performing their function, press down vreliably all onr or other materialcoming in contact'with them.v

The lower part, or about. one-halof theshaft G is made of acircularforruation, while'rthe upper portion, except -its extrme end, ismade square or aug.nlar. i y A The ltop part of theshaft Gr is madecircular, and is provided with a netallie washer, hung either loosely ormade fast with `the'shaft, yas maybe desired..

' H is a band-wheel, hung looselyfupon and isthe means whereby .the.vertical'shaft G is revolved, while theilour or other material is beingpacked.

This band-wheel 4H is` formed on provided with projecting armsorangeshlaand may embrace the vertical shaftxGgtheentire `4distance between thetwo cross-beams 0.0.'

The opening-ork space -inf the center of the `bandl wheel, and its armsor vlanges','is made of a form. corresponding tothe square or angularportion ofthe shaft G, so that, when the power is applied 'to the'band-wheel, by meansof a belt attached Ato a suitable pulley, the shaft`will revolve with it while packing the nour or other substance, butwhen the shaft is raised, until the circular portion of the verticalshaft enters the opening in the band-wheel and its arms or flanges, thelatter will revolve while the shaft remains stationary.

This is an important function', as it not only allows the ready.attachment of an empty sack, bag, or other package, when the one on thecase is packed as full as desired, but also saves power and machinery,there being no resistance offered by the vertical shaft duringthe-intervals of placing and replacing. the sacks, bags, or otherpackages upon the case. M M are arms, arranged transverse between thelcross-beams C C, and are'provided with circular openings O, seen indotted lines, of a diameter greater than that of the arms or flanges 7:Ah of the bandwheel,in such a manner that the said arms or flanges of theband-wheel are embraced and supported by the circular openings of thearms O C, at the same time not'interfering with the free revolution ofthe bandwheel. ,l

' These arms M 'M are provided near their outer ends with openings a c,for a purpose vhereinafter to be mentioned.

D D are upright standards or connections sliding freely up and down inthe openings a a of the cross- 'beam G .G and the openings e c, in thetransverse arms M. M. l

F is a case, made either of metal or wood, as may be desired, and uponwhich case the bag or sack to be packed is placed.

The upright connections D D arc secured to the A`inner surface of thecase F by. means of bolts or screws,

and extending upward pass through the openings a a and ce, and are theneither `secured firmly to the top `plate I or pass tln'ough-openings gg, formed in said when placed upon thercase, and its e'nds fasteued'to--gether by means of suitable hooks or catches.

r.ihe several parts'cemposing this packer are made either of cast,wrought, or other suitable metal, although wood can bc used in itsconstruction.

I am aware that conical rollers of equal size have ,long been known andused in machines for packing flour and like materials, but such I do notclaim.

'I am aware, too, that broad band-wheels or drums have been used forrot-ating the shaft carrying packing-rollers of equal size, but theyhave been uniformly keyed fast to the shaft, consequently t-he rotationof the one could not be stopped without stopping the i rotation of theother.

I am also aware that cog-wheels, provided and combined withsliding-sockets, clutch-pins, friction-rollers, and various otherclutching devices for stopping the rotation of the shaft carrying thepacking rollers when raised to a certain height, without discontinuingthe rotation of said operating wheels, have been known and used, butthese have proved to be` too complicated and expensive `in constructionand uncertain in action, and I disclaim all such.

I am not aware, however, that an arrangement for accomplishing thedesirable object above stated so cheap and simple in construction', andcertain. in function as mine, has ever-before been devised.

Having thus described my invention,

WVhatI claim as new, and desire to secure by Letters Patent, is

1. The combination and arrangement in a machine for packing flour andlike material, ot' the conical dif-' ferential rollers K K', andrevolving shaft G, substantially as described, and for the purpose setforth.

2. The band-wheel H, provided with the shoulders h, and an angularopening through its center, in combination with the vertically slidingshaft G and arms M, when said parts` are 'constructed and arranged tooperate substantially as described, in 4the manner and for the purposespecified and shown.

3'. The machine for packing iour and like material herein shown,consisting ofthe frame A B, crossbeams C, sliding standards D, arms M,wheel H, shaft G, case F, and plate l), constructed, combined, andarranged for operation, snbstantiallyas described.

To the abovel have signed my name this 24th'dzty of May, 1870. i
